【Abstract】 Water level measurement system is a distributed control system with PC as epigyny computer and 4 single-chip microcomputers as hypogyny computers.In this paper,a new method to realize serial communication among epigyny computer and hypogyny computers was demonstrated,the serial communication programe developed with VC++6,0 was introduced in detail, and the primary source code was also given. It has been proved that the system is steady and reliable,also has high precision.更多还原
